I have the same problem, as I moved from Ubuntu 16.04 to 18.04 I experienced a tremendous slowness when opening folders containing lots of files. While I did not find any actual solution, I put together a workaround that I wanted to share here as I think someone might find it useful. I'll appreciate any comment or suggestion.
